Abstract

Claims (22)

1 . A wearable ring device, comprising:

an inner shell forming an inner surface of the wearable ring device that is configured to at least partially contact a user when the wearable ring device is worn by the user, wherein the inner shell comprises at least a curved portion and a flat portion;

an outer shell that at least partially surrounds the inner shell, the outer shell comprising a continuously curved outer surface of the wearable ring device;

a light guide disposed between the inner surface and the outer shell, the light guide configured to emit light through the continuously curved outer surface of the outer shell, through one or more sidewalls extending between the inner shell and the outer shell, or both;

one or more sensors configured to acquire physiological data from the user, wherein the one or more sensors are disposed at least partially within the flat portion; and

a curved power source disposed at least partially between the inner surface and the outer shell, wherein the curved power source is configured to provide operating power to the one or more sensors.

2 . The wearable ring device of claim 1 , further comprising:

one or more charging pins disposed at least partially on or within the inner shell, wherein the one or more charging pins are configured to connect to an external power source to charge the curved power source within the wearable ring device.

3 . The wearable ring device of claim 1 , wherein the one or more sensors comprise a temperature sensor configured to acquire temperature data from the user.

4 . The wearable ring device of claim 3 , wherein the temperature sensor is disposed at least partially within the flat portion.

5 . The wearable ring device of claim 1 , wherein the one or more sensors comprise an accelerometer configured to acquire motion data from the user.

6 . The wearable ring device of claim 1 , wherein the one or more sensors comprise a heartbeat sensor configured to detect a heartbeat from the user.

7 . The wearable ring device of claim 1 , wherein the one or more sensors comprise a light-emitting diode (LED) configured to acquire the physiological data from the user.

8 . The wearable ring device of claim 1 , further comprising:

a printed circuit board coupled with the curved power source and disposed at least partially within the inner shell, wherein the one or more sensors are coupled with the printed circuit board.

9 . The wearable ring device of claim 1 , wherein the outer shell defines an O-shaped outer circumferential surface of the wearable ring device.

10 . The wearable ring device of claim 1 , wherein the outer shell comprises a metallic material, a plastic material, a ceramic material, a non-conductive material, or a combination thereof.

11 . The wearable ring device of claim 1 , further comprising a printed circuit board, wherein the one or more sensors are disposed on the printed circuit board, wherein an inner wall of the outer shell comprises one or more alignment structures configured to engage the printed circuit board to maintain the printed circuit board between the inner shell and the outer shell.

12 . The wearable ring device of claim 11 , wherein the one or more alignment structures are inserted into one or more holes within the printed circuit board to maintain the printed circuit board between the inner shell and the outer shell.

13 . The wearable ring device of claim 1 , wherein the outer shell comprises one or more geometric features etched into the outer shell, wherein the light guide is configured to emit the light through the one or more geometric features.

14 . The wearable ring device of claim 1 , wherein the light guide comprises one or more photoluminescent quantum dots, one or more fluorescent materials, or both.

15 . The wearable ring device of claim 1 , wherein the inner shell comprises a transparent potting compound that forms at least a portion of the inner surface of the wearable ring device and at least partially surrounds the one or more sensors, and wherein the transparent potting compound comprises silicone, epoxy, latex, plastic, or any combination.
